There used to be a custom of not stepping on the threshold. You can sit on the threshold and never step on it. Children are not sensible and often play on the threshold. When adults see it, they will immediately stop it, saying that the threshold is the god who protects the family and cannot be stepped on casually.
There are three common thresholds:
One is directly fixed in the groove of the door pillow stone, which is small in height and can be crossed in one step;
The second type is movable. If necessary, it can be inserted into the wooden slot on the door pillow stone or bolted between the two pillows with wooden pegs, with a height of about two feet.
The three thresholds are a pair of small doors that can be opened and closed freely under the gate. The height is generally more than three feet, and some even reach six or seven feet. There will be a small wooden or stone threshold two or three inches high under the small door.
The threshold of a lattice door is usually embedded between two columns, which is as long as the width of the bay. The bay is often equipped with door bolts, rabbits or wooden door pillows.
Threshold is of great significance in geomantic omen. In traditional buildings in China, there is always a threshold at the entrance of the gate. Its role in geomantic omen is to prevent external unfavorable factors from entering the home and preventing brain drain.
The threshold is the god to protect the family. Never step on it. Give people a feeling of being at home. There are thresholds that can be moved at any time, but you can sit and lie through the door.
If you come on foot. There used to be a custom of not stepping on the threshold. Step forward, step back, the threshold is not so symbolic. If you come by car on horseback, it will be considered rude. According to the custom of old Beijingers, it is the dividing line between the inner area and the outer area. It is a symbol to stand on the wall and watch the guests get on the sedan chair immediately. It should be said that people now live at home, and some big families go in and out for the convenience of horses and chariots.
There are two kinds of thresholds, fixed and movable, to ensure the safety and happiness of the family. But in the past, this was a very common thing. If the guests are just sent out of the house and not out of the threshold, then their understanding of the threshold is very unusual. Keeping all the bad things out of the door and crossing a threshold at the door is generally based on a fixed threshold, and there are also many stresses. First of all, the threshold has the function of shielding dirt and avoiding evil spirits. Threshold is also called threshold. It often plays on the threshold, and adults will stop it immediately when they see it. When seeing the guests off, you must send them outside the threshold, especially to drive those ghosts away.
The threshold was originally used to keep out the rain, but later it was expanded, which blocked both money and life, so when a person was not happy, he said, "I met the threshold." There is an old folk saying that the year of birth is a "threshold". It is said that there are many people and things this year, so you should be extra careful in your life. The root red belt to ward off evil spirits is to cross this "threshold". Others describe the age of 73 and 84 as the "threshold" for the elderly. The so-called "seventy-three, eighty-four, the ghost king doesn't ask himself to go"; It is also said that "Confucius is seventy-three and Mencius is eighty-four", which means that this "threshold" has also been fulfilled in Confucius and Mencius. People say that if you break through the threshold of 73, you will live to 84; You will live a long life after 84.
Another point is related to the threshold, that is, to go to the temple, the male guest must take the left foot first, and the female guest must take the right foot first, and no mistakes can be made. Male guests left their feet into the pure land of the west, while female guests right their feet into eighteen layers of hell. On the contrary, he must not be careless. Also, don't step on the threshold, it will make people float in yin and yang, can't become a god, can't be born.
